The Sensor Web initiative develops and implements wireless technology for distributed sensing and actuation in horticultural enterprises. The heart of the sensor web is the "node", a low cost, self contained integration of radio and microprocessor that interfaces sensing and actuation devices. Networking software allows deployed nodes to automatically find each other and create paths to route data and command actuation. The result is an inexpensive, easily installed system that monitors environmental data and implements remote (or even automatic) actuation of sprinklers, fans, heaters, and other devices.
